Used as a Grignard reagent in organic synthesis, it facilitates the formation of carbon-carbon bonds, particularly in the production of complex organic molecules. It is employed in the alkylation of ketones, aldehydes, and esters to create alcohols and other derivatives. Additionally, it serves as a key intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. Its ability to introduce long alkyl chains makes it valuable in modifying surface properties of materials, such as in coatings and surfactants.
